Build Status


John Snow Labs Spark-NLP is a natural language processing library built on top of Apache Spark ML. It provides simple, performant & accurate NLP annotations for machine learning pipelines, that scale easily in a distributed environment.

This library has been uploaded to the spark-packages repository .

To use the most recent version just add the --packages JohnSnowLabs:spark-nlp:1.6.1 to you spark command

spark-shell --packages JohnSnowLabs:spark-nlp:1.6.1
pyspark --packages JohnSnowLabs:spark-nlp:1.6.1
spark-submit --packages JohnSnowLabs:spark-nlp:1.6.1

Jupyter Notebook

export SPARK_HOME=/path/to/your/spark/folder

pyspark --packages JohnSnowLabs:spark-nlp:1.6.1

Apache Zeppelin

This way will work for both Scala and Python

export SPARK_SUBMIT_OPTIONS="--packages JohnSnowLabs:spark-nlp:1.6.1"

Alternatively, add the following Maven Coordinates to the interpreter's library list


Python without explicit Spark installation

If you installed pyspark through pip, you can now install sparknlp through pip

pip install --index-url spark-nlp==1.6.1

Then you'll have to create a SparkSession manually, for example:

spark = SparkSession.builder \
    .config("spark.driver.maxResultSize", "2G") \
    .config("spark.driver.extraClassPath", "lib/sparknlp.jar")\
    .config("spark.kryoserializer.buffer.max", "500m")\

S3 Cluster with no hadoop configuration

If your distributed storage is S3 and you don't have a standard hadoop configuration (i.e. fs.defaultFS) You need to specify where in the cluster distributed storage you want to store Spark-NLP's tmp files. First, decide where you want to put your application.conf file

import com.johnsnowlabs.uti.ConfigLoader

And then we need to put in such application.conf the following content

sparknlp {
  settings {
    cluster_tmp_dir = "somewhere in s3n:// path to some folder"

Pre-compiled Spark-NLP and Spark-NLP-OCR

You may download fat-jar from here: Spark-NLP 1.6.1 FAT-JAR or non-fat from here Spark-NLP 1.6.1 PKG JAR Spark-NLP-OCR Module (Requires native Tesseract 4.x+ for image based OCR. Does not require Spark-NLP to work but highly suggested) Spark-NLP-OCR 1.6.1 FAT-JAR

Maven central

Our package is deployed to maven central. In order to add this package as a dependency in your application:




libraryDependencies += "com.johnsnowlabs.nlp" % "spark-nlp_2.11" % "1.6.1"

If you are using scala 2.11

libraryDependencies += "com.johnsnowlabs.nlp" %% "spark-nlp" % "1.6.1"

Using the jar manually

If for some reason you need to use the jar, you can download the jar from the project's website:

From there you can use it in your project setting the --classpath

To add jars to spark programs use the --jars option

spark-shell --jars spark-nlp.jar

The preferred way to use the library when running spark programs is using the --packages option as specified in the spark-packages section.

Downloading models for offline use

If you have troubles using pretrained() models in your environment, here a list to various models (only valid for latest versions). If there is any older than current version of a model, it means they still work for current versions.

Updated for 1.6.1
